globalmapper.ExportElevation
============================

.. currentmodule:: globalmapper
.. py:function:: ExportElevation (str aFilename, GM_ElevationExportFormat_t32 aFormat, GM_LayerHandle_t32 aLayer, GM_Rectangle_t aWorldBounds, sint32 aPixelWidth, sint32 aPixelHeight, GM_RasterExportFlags_t32 aFlags, GM_ElevUnits_t8 aElevUnits) -> GM_Error_t32

    Exports one or more layers to a new gridded elevation file. If gm.NULL is passed for the layer handle, all elevation
    layers will be saved to the new elevation file, otherwise only the specified layer will be exported. If None is
    provided for the world bounds, all available data will be exported, otherwise only data within the specified bounds
    will be exported.

    The new elevation file create will be in the current view projection as returned by the
    :doc:`GetProjection<../measure/globalmapper.GetProjection>` function. You can change the view projection, and thus
    the export projection, by calling the :doc:`SetProjection<../measure/globalmapper.SetProjection>` function.

    :param str aFilename: Name of new file to create
    :param GM_ElevationExportFormat_t32 aFormat: Format to export
    :param GM_LayerHandle_t32 aLayer: Layer to export or gm.NULL for all
    :param GM_Rectangle_t aWorldBounds: World bounds to export or None for all
    :param sint32 aPixelWidth: Width in samples of new image
    :param sint32 aPixelHeight: Height in samples of new image
    :param GM_RasterExportFlags_t32 aFlags: Export flags
    :param GM_ElevUnits_t8 aElevUnits: Elevation units for export, if applicable
    :returns: Error Code
    :rtype: GM_Error_t32
